Call me "old school",BUT its winter, why a arf? or a rtf theres plenty of time before great weather gets here, father an son project build a plane. What a original idea. There are so many out there that fly an build easy. Most kits are cut with a cnc or lazor. no more die smashed parts, the parts fit great. the covering is easy. Not only will they bond , but they will learn a few things along the way. just my thoughts. ill offer any help i can, not just take , as will others that build.
